Weight LossTrending
High evidence

Semaglutide

GLP-1 receptor agonist widely used for weight management and glycemic control. The most clinically studied peptide in this class with multi-year outcome data.

Weight LossTrending
High evidence

Tirzepatide

Dual GIP/GLP-1 agonist showing superior average weight-loss efficacy versus semaglutide in head-to-head and parallel trial programs.

Healing
Moderate evidence

BPC-157

Body protection compound studied for regenerative and gut-healing properties. Evidence is extensive in animal models; human clinical data remain limited.

Healing
Emerging evidence

TB-500

Thymosin beta-4 fragment associated with wound healing, cell migration, and tissue repair in preclinical literature.

Growth
Moderate evidence

CJC-1295

Growth hormone releasing hormone analog designed to elevate GH and IGF-1 with extended activity versus native GHRH.

Growth
Moderate evidence

Ipamorelin

Selective growth hormone secretagogue with a cleaner side-effect profile than earlier GHRPs in comparative research.

Growth
Moderate evidence

GHRP-6

Growth hormone releasing peptide that also strongly increases appetite — useful or limiting depending on the goal.

Tanning
Limited evidence

Melanotan II

Synthetic melanocortin peptide that stimulates melanogenesis and has secondary effects on appetite and libido.

Libido
High evidence

PT-141

Melanocortin receptor agonist (bremelanotide) used for hypoactive sexual desire via central pathways rather than vascular mechanisms alone.

Longevity
Emerging evidence

Epitalon

Synthetic tetrapeptide related to epithalamin, linked in exploratory research to telomere and circadian biology markers.
